Hello all,
I am trying to get automatic networking provisioning for local
zones working, ultimately in order to simplify rapid deployments
of testbeds and per-bug build environments.
In the process I found a few nits, and wondered if I am doing
something wrong or things are according to current design and
that can be revised, perhaps? So, here goes:
A few more:
4) If I pre-configure the local zone with /etc/sysidcfg
(created between installation and first boot), and use
network_interface=PRIMARY {dhcp protocol_ipv6=no}
then the interface is first attempting "auto-revarp"
configuration and sends out RARP packets (not served
by Sun DHCP) and then sends out DHCPREQUESTs as asked.
If I don't provide the /etc/sysidcfg file, RARP is
still attempted, times out and "in.rdisc" failure is
logged, then the wizard asks for static IP settings.
I wonder if it is possible to either tie in the RARP
replies to Sun DHCP server, or to have the new client
attempt DHCP by default - since it does use RARP?..
(perhaps with a smaller timeout than 300sec waiting
with explicitly requested DHCP setup).
5) Is it possible to make a hands-free installation
(without supplying a /etc/sysidcfg manually) perhaps
distributing all these settings via DHCP (in private
options and/or as an URL to fetch the file via HTTP
or TFTP) - *if* DHCP and/or the DNS resolution setup
would now be also requested by default? ;)
I am thinking towards Sun Ray DTU auto-configuration
with a mix of DHCP and DNS settings for predefined
names (i.e. sunray-server-config.yourdomain.com).
